Having built and used several of these type of stoves I would have to recommend staying away from the white gas. It is very volatile and with so many other cheaper fuels out there, HEET, rubbing alcohol, denatured alcohol(the best) there is really no need to experiment with white gas. Just my opinion.

Denatured alcohol burns very clean and hot. I boiled 4 cups of water in less than 5 minutes with about 3-4 tablespoons.

Rubbing alcohol will burn but is a bit sooty because of the water content...but it will heat and boil water, just takes longer.

Grain alcohol can be used..but it's really the most expensive since it is suitable for human consumption whereas the others are not.

HEET burns but is sooty and has funny oder..I would use this in an emergency.

Your best choice is the Denatured Alcohol. You can pick it up at you local hardware store or super store. One quart of the stuff should fuel all the stoves your scouts can build and it can be carried in a simple 20 oz plastic pop bottle with no fear of the container melting on you.

Also, depending on the style you build, you can turn the stove over and put an estibit tablet on the can and cook that way.

Wind screens are a must, but you can construct them out of heavy duty oven liner. My group has used them several times and the only frustration is A) having to come up with the pot support and B) not being able to turn it off.

Have fun, and if you do try the white gas...please be careful.
